Sunshade with retractable function

Abstract

A solar protection device capable of being reeled comprises a mounting unit, a solar protection unit and a reeling mechanism. The mounting unit comprises two spaced end seats, the solar protection unit comprises a reel, a curtain fabric and two linkage parts, the curtain fabric is reeled on the reel, by the aid of the two linkage parts, the reel capable of rotating along a self axis is erected between the end seats, the reeling mechanism is mounted on one of the end seats and comprises a torsion rotating wheel, a take-up and pay-off wheel and constant torsion spiral spring, the torsion rotating wheel is combined with one of the linkage parts in a linkage manner, and the constant torsion spiral spring is reeled on the take-up and pay-off wheel and leads the torsion rotating wheel to have reeling resetting force. The reeling mechanism is arranged on one of the end seats and accordingly can be mounted conveniently, furthermore, limitation to the size of the reeling mechanism can be avoided, and the reeling resetting force of the solar protection device is further increased.

Description

technical field [0001] The invention relates to a sunshade device, in particular to a sunshade device with a retracting function in which the cord can be retracted automatically. Background technique [0002] refer to figure 1 , 2 In the past, the sunshade device 1 basically includes two left-right symmetrical end seats 11, a housing 12 fixedly erected between the end seats 11, and a sunshade unit 13 rotatably erected between the end seats 11. , and a retracting mechanism 14 that enables the sunshade unit 13 to have a retracting function. The sunshade unit 13 includes a reel 131 that is passed through a channel 121 of the housing 12, a curtain 132 that is rolled up on the reel 131 and whose unfolded end protrudes from a slot 122 of the housing 12, a The positioner 133 installed on the unfolded end of the curtain 132 and the two linkage members 134 sleeved on the two shaft ends of the reel 131 are interlocking. The take-up mechanism 14 includes a mandrel 141 which is pass...

AI Technical Summary

Problems solved by technology

In the past, although the sunshade 1 can roll up the curtain 132, the mandrel 141 and the coil spring 142 that provide the reset retraction force are installed in the shaft channel 135 of the reel 131 with a small space. The retracting mechanism 14 of 1 is not only small in size and inconvenient to assemble, but also the wire diameter of the coil spring 142 cannot be too large, so its retracting force is poor
